In 1931 the crossover to get the inbound cars from Knoxville to the backtrack was removed because it was no longer needed.  There is no mention of a connection to the inbound track and maps of the era show only a connection to the outbound track.  Four years earlier, though, the Overbrook line was connected to the backtrack so that interurban cars could be routed to and from the city via Brownsville Rd. (Arlington Ave.).  There appears to be a missing link.
